We present a drilling method that is based on the phenomenon of local hot spot generation by near-field microwave radiation. The microwave drill is implemented by a coaxial near-field radiator fed by a conventional microwave source. The near-field radiator induces the microwave energy into a small volume in the drilled material under its surface, and a

This chapter demonstrates how the provincial realist novel incorporated exhaustion as a temporal structure to depict the new horizons of human life under extractivism. Provincial realism's longstanding reliance on the marriage plot and the inheritance plot, on providing closure via social reproduction, transforms against the backdrop of extractivism to

Development of intelligent drilling and intelligent drill tools
2011 6th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2011This paper introduces the principles and techniques of intelligent drilling which can be considered as a computer intelligent expert system with intelligent drill tools and information network system as the key technologies. In this paper, we have discussed the key technology of how to combine power transmission and high speed bidirectional information

A Brief History of Drills and Drilling
BEADS: Journal of the Society of Bead Researchers, 1998A microscopic examination of silicone impressions of the perforations of beads, sealstones, and amulets has produced a data base of characteristics that help to define what type of drill was used to make them. This article outlines the various types of drills that have been used from the Palaeolithic period to the present day, and notes what ...

To Drill Or Not To Drill: A Synthesis of Expert Judgments
2001Petroleum exploration is a costly venture which always involves a great deal of uncertainties and unknown factors. A decision to drill could result in a giant discovery, a modest discovery, or a dry hole. The factors influencing drilling decisions could be of geologic, economic and personal nature. When making a decision based on geologic factors alone,

The production of a hole in a mechanical component is usually done by using a drill. Although drilling a hole appears to be a simple operation, the accurate drilling of a hole of the right size at the right location, can be difficult. A large number of tools and machines have been designed for the drilling of holes economically, accurately, and quickly,

Gas Diagnostics: To Drill or Not to Drill?
Canadian International Petroleum Conference, 2004Abstract A very important but often difficult question to answer when dealing with gas reservoirs is: to drill or not to drill? Why are some gas pools only drilled at 2 wells/section and some drilled up to 16 wells/section? How do you decide whether downspacing will be beneficial? An accurate assessment of important
